Insurance billing

Insurance billing defines the process where a provider submits claims to insurers for payment of covered services. Medical practices, dental offices, and hospitals rely on billing codes like CPT and ICD-10 to document procedures and diagnoses.

Claims include patient information, dates of service, specific procedure codes, and the National Provider Identifier (NPI). Insurers use adjudication systems to determine if billed services match policy coverage limits and allowed amounts.

Delays often stem from coding errors, missing documentation, or mismatched patient details–over 20% of medical bills contain such errors according to the Medical Billing Advocates of America. Patients receive explanations of benefits (EOBs) detailing insurer payments and personal financial responsibility.

Providers appeal denied claims using standardized forms like the CMS-1500 or UB-04. Balance billing occurs when providers bill patients for the difference between charged and allowed amounts; federal law bans balance billing for emergency care under the No Surprises Act (2022).

Electronic billing methods process over 95% of Medicare claims, increasing speed and accuracy versus paper methods, as reported by https://yourinsurance.info. Coordination of benefits applies when patients have multiple plans; primary insurers pay first while secondary plans cover remaining eligible costs.

Insurance companies audit billing records annually to reduce fraud, flagging upcoded or duplicate charges through software algorithms.
